Web-based Data Mining
The Wall Street Warrior website houses your back-tested results. The integrated reporting platform generates reports and organizes them in the order in which you created them. The Back-Test Reports are very informative and give you a look inside the trading system, it's profitability and tradability. This also allows the user to mine the results to find higher probability trading scenarios.
Data-Mining
- This discussion only covers data-mining after back-tests have been performed. For Discovery Data-Mining, please see Data-Mining for Discovery.
- If you haven't read how to view the back-tests using the Wall Street Warrior's web-based reporting platform, please read Back-Test Reporting
The Wall Street Warrior web-based data-mining feature allows the user to define patterns, search for results on pattern dates or after pattern dates within their back-tested results sets stored on the server:
- Compare Mined back-tested results with each other
- Print Out Mined Back-Tested Results
- View Mined Trading System Statistics
- Download applicable code to use in the Wall Street Warrior - Coming Soon!
Data-mining is a very useful tool to any trader. The Wall Street Warrior's integrated web-based data-mining application allows users to increase profitability in their trading systems.
Define Symbol and Dates
The Data-Mining application allows the user to define a symbol and dates to search for defined patterns.
Here, we have selected to mine AAPL from 3/1/2003 to 12/31/2010 for a pattern that will be defined later in the page.
Pre-defined Patterns Selector
The Wall Street Warrior's data-mining application has 40 pre-defined patterns to choose from. This list is growing daily, and we expect to be near 100 patterns within the coming months.
User Defined Pattern Selector
The User Defined Pattern Selector is currently under construction. This will enable the user to define almost all elements of a pattern they would like to test against, including some technical indicators. The following will be available for variable inputs in this platform:
- Moving Averages
- Open / High / Low / Close
- RSI
- Patterns
- New Highs / New Lows
- X Day Highs / X Day Lows
- X Day Pullbacks from Highs / Lows
Searching Data
After you submit the rules that you want to check for, you click the 'Submit' button. The application will search through the database looking for the pattern selected and output the day that the pattern occurred as well as the following trading day. This will allow you to mine the data to determine the profitability of trading after this pattern.
Viewing Mined Results
The mined results show the day of the occurrence of the pattern that was entered as well as the day after the pattern. This allows the user to select which day he wants to see the data for. The only criteria that would be beneficial to you as a trader when looking to see the results for the day of the pattern would be when a Gap Open exists. Most other patterns would not likely be known at the time of the Open and you would not be able to trade off a pattern that you don't know exists.
Viewing Mined Back-Test Results
- Pattern Dates - Displays the Dates on which the pattern occurred.
- Next Dates - Displays the Trading Date after the pattern occurred.
- Show / Hide Patterns - Toggles between showing the Dates or Hiding them.
To view the Results Sets that you have back-tested, click on the 'Next Dates' cell at the top of the results. This will open a new page and will filter all of your back-tested results to show you the trading results for that method after the pattern occurred. If you choose a pattern that can be identified on the OPEN, such as a GAP, you can use the 'Pattern Dates' cell to view the results. This will show how the market would have traded on the Day of the Pattern.

Now, the back-tests show only the dates after the pattern occured. In this case, we chose an Outside Day Down and the back-tests that were performed now show only the results the trading day after an Outside Day Down occurred.
